my car has nomore power and now the tone of the exhaust sounds weak and isnt loud and mean like before. i have a buschur exhaust so its really loud but now no matter what gear or how much gas i give the tone of the exhaust sounds like if i was cruising. it sounds weak like something is wrong. what can cause the exhaust to sound like this? it's not an exhaust leak btw.

 

you got used to the sound.

 

Does it have a cat? Might have fell apart inside.

 

no cat, full turbo back. my car barely beat a stock jetta. wtf is wrong?

 

log it

That will tell you the story.

 

Something is DEFIANTLY wrong

Seriously though, that sounds strange. I can't think of anything other than possibly a clog in the exhaust, or possibly the manifold? Just and idea...

 

Unless it was the Jetta from The Fast and The Furious and Frankie Munez was driving.....

 

Yes! That is great.

 

boost leak..? hear any "pssssssssss" air sounds when hitting the gas..? can't always trust your boost gauge if the car doesn't feel right.

 

Maybe someone stuffed a plastic bag up your cat-back. Check to make sure if its clear

 

i also get a slight vibration around the whole car whenever the rpms get to 2500, my gas pedal is vibrating 24/7 nowadays. my turbo spools louder for some reason now and my stock dv seems louder too.

 

Do you have an intake?

If you have a stock intake and box, it's possible that maybe there is a leak, or possibly the box has become disconnected behind the MAF? That would cause viabrating and/or bucking due to unmetered air as well as cause your DV and turbo to be louder.

I'm not sure how that could cause a weaker exhaust note though

 

You car should of ate that Jetta for lunch!
